Step-by-step explanation:

To find the equation for the nth term in the sequence, we need to determine the pattern or rule that generates the sequence.

From the given information, we can see that the sequence is not arithmetic because the differences between consecutive terms are not constant. Instead, the sequence appears to be quadratic because the second difference between consecutive terms is constant.

Using the given values of a₁, a₃, and a₅, we can find the first few differences:

a₃ - a₁ = 4 - (-6) = 10

a₅ - a₃ = 14 - 4 = 10

So, the first difference is 10, which indicates a linear term in the equation for an. We can now use the given value of a₁ and the first difference to find the constant term in the quadratic equation. Let d be the common difference, then we have:

a₂ = a₁ + d = -6 + 10 = 4

a₄ = a₃ + d = 4 + 10 = 14

a₆ = a₅ + d = 14 + 10 = 24 - 1

a₇ = a₆ + d = 24 - 1 + 10 = 33

Now, we can find the second difference between consecutive terms:

a₄ - 2a₃ + a₂ = 14 - 2(4) + (-6) = 0

a₆ - 2a₅ + a₄ = 19 - 2(14) + 4 = -5

a₇ - 2a₆ + a₅ = 33 - 2(19) + 14 = 9

Since the second difference is constant (-5), this confirms that the sequence has a quadratic term in its equation. Let's assume the equation for the nth term is:

an = an² + bn + c

Substituting the values we know, we get three equations:

a₁ = a₁² + b₁ + c --> -6 = c

a₃ = a₃² + b₃ + c --> 4 = 9a + b + c

a₅ = a₅² + b₅ + c --> 14 = 25a + 5b + c

Solving this system of equations, we get:

a = 1/2, b = 19/2, and c = -6

Therefore, the equation for the nth term in the sequence is:

an = (1/2)n² + (19/2)n - 6.

It’s about 0.3773.

Having a contract with provider B and not having cell phone are independent events.

A probability is calculated as the division of the desired number of outcomes by the total number of outcomes in the context of a problem/experiment.

If two events are independent, the multiplication of the probabilities of each event is equals to the probability of both events happening.

The probabilities for this problem are given from the table as follows:

The multiplication of the probabilities of each event is:

84,800.45x10= 848,004.5 you move the decimal one place to the right

45.67÷1,000= 0.04567 you move the decimal two places to the left.

The inequality is used to find the domain of the given function is

5x-5 ≥ 0

A function is a relation from a set of inputs to a set of possible outputs, where each input is related to exactly one output.

Given is function y = √(5x-5)+1, we have to find which inequality can be used to find the domain.

Since, the function is a square root function.

We know that,

The square root function is defined only for the positive values, including 0. i.e. the expression inside the square root must be greater than or equal to 0.

The expression inside the square root is (5x-5) so that must be greater than or equal to 0 which can be written as :

5x-5 ≥ 0

Hence, the inequality is used to find the domain of the given function is 5x-5 ≥ 0

Answer:

Step-by-step explanation:

This is a test of 2 population proportions. Let 1 and 2 be the subscript for the women that responded positively at the earlier and later survey. The population proportion of women's positive responses at the earlier and later survey would be p1 and p2 respectively.

p1 - p2 = difference in the proportion of women's positive responses at the earlier and later survey.

The null hypothesis is

H0 : p1 = p2

p1 - p2 = 0

The alternative hypothesis is

Ha : p1 > p2

p1 - p2 > 0

it is a right tailed test

Sample proportion = x/n

Where

x represents number of success

n represents number of samples

For earlier survey,

x1 = 2010

n1 = 3000

p1 = 2010/3000 = 0.67

For later survey ,

x2 = 1530

n2 = 3000

p2 = 1530/3000 = 0.51

The pooled proportion, pc is

pc = (x1 + x2)/(n1 + n2)

pc = (2010 + 1530)/(3000 + 3000) = 0.59

1 - pc = 1 - 0.59 = 0.41

z = (p1 - p2)/√pc(1 - pc)(1/n1 + 1/n2)

z = (0.67 - 0.51)/√(0.59)(0.41)(1/3000 + 1/3000)

z = 12.6

From the normal distribution table, the probability value corresponding to the z score is less than 0.00001

Therefore,

p < 0.00001

By using the p value,

Since 0.05 > the p value, we would reject the null hypothesis. Therefore, at

the .05 level, can we can conclude that women think men are less kind, gentle, and thoughtful in the later survey compared with the earlier one

Answer:

\(2,8,14,20\)

Step-by-step explanation:

If the first term of a sequence is \(2\) and the common difference is \(6\), then each successive term in the sequence is \(6\) more than the previous term:

\(a_n=6n-4\)

Therefore, the first term is \(2\), followed by \(8\), \(14\), and \(20\).

The area of triangle ADE is,

⇒ A = 48 square units

We have to given that,

In the diagram , DE is a midsegment of triangle ABC.

And, The area of triangle ABC is 96 square units

Now, We know that,

Since DE is a midsegment of triangle ABC, it is parallel to AB and half the length of AB. Therefore, DE is half the length of AB.

Hence, the area of triangle ADE is half the area of triangle ABC,

That is,

A = 96 / 2

A = 48 square units

The probability for the dial stops on a red or blue slice is,

P = 7/8.

Since, We know that;

Probability is to measure of the likelihood of an event occurring.

Hence, It is a number between 0 and 1,

Since, The closer the probability is to 1, the more likely the event is to occur.

Hence, Probability can make predictions and decisions in various fields, including finance, statistics, etc.

Since, There are 4 red and 3 blue slices,

Hence, a total of slices,

= 4 + 3

= 7 slices that are either red or blue.

So, The probability of the dial stopping on a red or blue slice,

Probability = ( red or blue slices) / (total of slices)

Probability = 7/8

Therefore, the probability for the dial stops on a red or blue slice is 7/8.

Answer:

f. cross-sectional sample survey

Step-by-step explanation:

- longitudinal cohort study is when the group of subjects that comprises the cohort is chosen based on a disease or injury and is then monitored over time at routine intervals. In this question, it's not the case as the sample of men were just picked and studied with no special group or cohort.

- If it was case-control observational study, the research would have started with identifying those who have heart failure and those who don't have heart failure but it wasn't the case and thus this is not correct.

- If this was voluntary response sample, it means the men would have been self chosen which means they volunteered to be part of the study if it was of interest to them. But this is not the case here.

- If it was completely randomized experiment, it means that the people sampled would have been randomly assigned to different treatments which was not so in this question.

- If it were to be match pairs experiment, it means the men sampled would be grouped into pairs and each pair will be assigned different treatments which didn't happen in this question.

- If it were to be cross-sectional sample survey, it means that data will be collected from a population of interest to make inferences from that population at a point in time. That is the case here because data about sedentary time or less was taken and compared to know the effect it had on heart failure.

- If it were census, it will just be about getting the size of the population without making inquiries about sedentary time.
